Abstract

We have used selective excitation and monitoring of individual (

J, m_{J}

) Zeeman sublevels of the

4 {}^{2}P_{\frac{1}{2}}

and

4 {}^{2}P_{\frac{3}{2}}

states of K at 22 and 131 kG to measure (

J, m_{J} \to J^{'}, m_{J^{'}}

) transition cross sections for K colliding with He, Ne, and Kr, at 380 K. The results, translated into irreducible tensor cross sections for depolarization are, in units of

10^{- 16}
